Preferably to the friends from UK: What is the best preparation method for a Pterichthyodes milleri from the Devonian of Achanarras? Carbide tipped graver, air scribe or abrasive blaster? And if you can use an abrasive blaster, which abrasive is best? The fish is still almost completely covered and lies in a devilishly hard and thick slab. I want to prep the fish from the other side. What you see here should be the ventral side. What do you think? @Terry Dactyll, @Kosmoceras, @James_R_V

Have been investigating a Pleistocene archaeological site here in the Northern Shenandoah Valley of Virginia. This double burin was found recently. Can the fossil on this be identified, or is it a generic shell?
